Er . . . uh. . . .   I'm afraid I have to disagree with Richie. Sorry, Richie.

I have also been teaching guitar (since the mid-1950s), and I would at least postpone getting an electric guitar until your son learns to play an acoustic. My reasons are similar to my objections to the idea of a left-handed guitar. If he learns to play an acoustic guitar first, the techniques are directly transferable to an electric.   It also works the other way, but not quite as easily, partly because the action of an electric guitar is lighter.

And--believe it oo not, there are places in this world where there are no wall-plugs!!   With an electric guitar, no wall-plug, no music!

There's no law that says one can't play both an acoustic and an electric. But it's better to learn on an acoustic.

I could go on and beat my usual drum about it being really best to start with a nylon-string classic and learn some classic technique first (technique that is transferable to any style(s) of guitar playing), like Stilly River Sage's young'un is very wisely doing, but I'll just shut up now.
